Valuable information otherwise not in our collections is made available to all users by access to the Internet. Internet sources change and grow rapidly, and accuracy and authoritativeness are not consistent. The Library selects specific sites to link to from the Library's Web site, which are consistent with the Library's materials selection policy. The Library makes every effort to direct users to such sites through promotional materials, staff instruction, or the catalog. Parents or guardians are responsible for the Internet information accessed by their own children. Appropriate use of the Internet is described in current operating guidelines.
